Specification of Letters Patent.

Application filed December 20, 1910.

Patented Dec. 12, 1911.

Serial No. 598,450.

To all whom it may concern: I

Be it known that I, LESTER O. CARTWRIGHT, a citizen of the UnitedStates, residing at Springfield, in the county of Sangamon and State ofIllinois, have invented a new and useful Churn-Dasher, of which thefollowing is a specification.

My invention relates to dashers for churns of the class employingrotating dashers.

The purposes of the invention are: to provide a dasher of improvedconstruction; and to provide means to facilitate the attaching anddetaching of the dasher.

The invention is illustrated in the annexed drawing to which referenceis hereby made.

The novel features of construction will now be described and finallyrecited in the claim.

The fixed standard 5 has in its lower part a vertical bore 5 adapted toaccommodate the hub 6 of the gear-wheel 6. The gear 6 meshes with and isdriven by the gear 8 and has an elongated hub 6 adapted to turn in thevertical bore 5 of the standard 5. The hub 6 has a central hole 6* whichis circular in its lower part and tapering and square in its upper part.

The dasher 15 is a worm-shape metal bar of suitable dimensions having atits lower end an integral relatively broad blade 15 and having near itsupper end a tapering square part l5 fitting in the square part of thehole 6 a tapering cylindrical part 15 adapted to turn in the cylindricalpart of the hole 6 and a screw threaded part 15 on which a thumb nut 16fits. Upon screwing down the thumb nut 16 the parts will be firmlyconnected so that the dasher will rotate with the gear 6; and uponloosening the nut the dasher may be detached from the gear. Thisconstruction gives the parts a firm connection. The parts are of suchform that they may be easily cleaned and may be easily detached forstorage or transportation. For sanitary reasons, the form of the partsand the convenience of attachment or detachment of the parts forcleaning is of prime importance.

A feature of special merit is that the relatively wide blade 15 servesto thoroughly agitate the cream in the lower part of the churn andthereby maintain constant flow of the cream and greatly facilitateaeration thereof.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is A spiral dasher having at its lower end arelatively wide blade and having at its upper end a tapering polygonalpart for connecting with the dasher a gear for rotating the dasher and ascrew-threaded part adapted to receive a nut for securing the gear onthe dasher.

In witness whereof I have hereunto signed my name at Springfield,Illinois this 14th day of November 1910.

LESTER O. CARTWRIGI-IT.
